FORM CARRIER FOR DRYING MACHINES.

Application filed June 5, 1924, Ser1a1 No. 717,944. Renewed January 11, 1928.

This invention relates generally .to drying machines and more particularly to that type embodying an enclosure through which pivotally mounted forms are intermittently 5 progressed, and means operative concurrently with successive progressions to swing individual forms in opposite directions to effect exterior presentation and re-entry relative to the enclosure. 7

An important object of this invention is to provide a simple and effective means whereby inspection of the articles to be dried during placement on the forms may be accomplished with ease.

Another object is the provision of a novel means, functional to prevent displacement of the drying forms relative to their supports during the operation of stripping.

A further object is to effect the automatic placement of successive forms with predetermined directional disposition preceding entry into the drying enc osure or, in other words, the series of drying forms are consecutively n'ogressed through the drying en- ,closure without. reversal, irrespective of any directional deflections incident to boarding inspection.

Other objects and attendant advantages inhering to our invention will be hereinafter referred to, or become obvious from the following description of one practical embodiment thereof, the. same having been chosen from other possible forms as best adaptedto clearly feature its characteristics and modus operandi.

In the drawings, constituting a part here- ;of, like parts are distinguished by the same reference characters in all the views.

Fig. VIII, is a fragmentary plan, of the means effective to return successive forms to predetermined planal relation, prior to. entering the drying enclosure.

Before entering into a detailed explanation of the present invention, and in order that its true perspective may be appreciated, attention is drawn to the fact that said invention is particularly-though not essentiallywell adapted for application to drying machines comprising a cylindric enclosure 9, having an annular corridor 10, through which a'series of forms 11, are adapted to be progressed by means of an intermittently moved horizontally rotatable spider, fragmentary portions of the arms whereof are characterized by the numeral 12, it not being deemed essential to fully illustrate the same; as anyone but slightly acquainted with the art will fully comprehend its structure without specific illustration and descriptive matter. Secured around the periphery of the horizontally rotatable spider 12, at equal distances apart,

by means of lock nuts 13, 1 1, are a series of king-bolts l5 functional as stationary pivots for outrigger arms 16,. These outrigger arms 16, are each .of upwardly inclined character and somewhat cruziform cross-section to afford the necessary strength and rigidity, and are each provided with an integral elongated hub portion 17, by means of which they are fulcrumed to the king-bolts 15 intermediate the head 18 thereof, and the lock nut 13. It will, of course, be readily understood that the lock nuts 13., 14 provide for vertical adjustment .of the outrigger arms 16, as well as affording means whereby said arms may be readily removed and replaced.

Integral with the hub portion 17, aforesaid, are superposed lateral lugs 19, 20,,of the relatively irregular configuration, best shown by Figs. VI and V, respectively. These lugs .19, 2.0 cooperate, with instrumentalities later on fully described; while the machine is provided with a laterally projecting framework 21, affording support for a trip device, 22, fashioned with relatively stepped teeth 23,62 1 whereby each successive form 11 receives a half-turn, as hereafter explained in detail, so that said form re-enters the drying corridor 10, with the same planal direction it emerged therefrom.

Each outrigger arm 16, is formed at its outer and upper end with a somewhat boxlike or pedestal bearing 25, functional as a swivel support for the pivotally mounted form carrier, comprehensively designated by the numeral 26; and said bearing is reinforced, relative to the outrigger arm 16 by a tin 27. As best seen by F igs. II and Hi, the bearing embraces an upwardly directed cylindric extension .28, having diametrically opposed cams or teeth 2.), with which engage the reversedly directed complcmental cams or teeth on the form carrier 26. This form carrier 26, it will be seen, com: prises an upper or sleeve portion 31 with a co-extensive shroud 32, the latter having laterally directed teeth 33, 34; the purpose whereof will be later on explained, while on the top face of said form carrier there is provided a cam path 35 functional as a stop for engagement by a latching device, comprehensively designated by the numeral 36. and best shown in Fig. VII. The i'orm carrier 9.6 is also fashioned with integral angular flanges 37, having reinforcements 38 which project slightly beyond the vertical edges 01 said flanges, as clearly indicated in Figs. 11 and 171i. 'lransversely oi the outer vertical face of the flanges 37, there is formed a lip 39, serving as an abutment for the lower edge of the form 11, which is removably attached thereto, by means of tap bolts a0, having wing nuts 41, with interposition of an angle section -12 and spring washer 43. It is noteworthy at this juncture, that the pedestal bearing and form carrier 26 are co-axially aligned at a slightangular inclination over from the vertical, to aid the operative when clothing the form 11 with awet article to be dried. Furthermore, attention is drawn to the stepped relation of the horizontal portions of the angular flange 37 and angle-section 42, which ailords a slight overlap between said flange and angle-section elements of consecutively adjoii'ung torm carrier units during progression around the annular corridor 10, as indicated at at in Fig. I, which closes in the bottom oi said corridor and thereby prevents wastel'ul escape of the drying medium. Swiveling connection between the bearing 25, and form carrier 26, is afforded through the instrumentaiity of a bolt 15, the head 16 whereof is countersunk into the upper part of the sleeve portion 31, and its lower shank portion is encircled by a butler spring 47, abutting between the inner end of the cylindric extension 28, and a nut 48, threaded on the free end of said bolt. Locking oi the nut 18, in adjusted position, is ell'ected by means of a jack sit), and it will be readily apparent that the spring 17, is placed under just suflicient compression to permit what we C011 veniently termhelico-axialmovement of the form carrier 26 relative to the bearing 25, as later on set forth.

eierring to the latching device 36, which is best shown in Fig. VII, it will be seen the same comprises a pedestal 50, having a basal flange 51, by means of which it is securedby bolts 52on the laterally projecting frame 21, hereinbetore referred to. The pedestal is formed at its upper part with an integral horizontal overhang .73, and spaced apertured flanges 5st, functional as guides for a longitudinally slidable bolt 53 having a rectangular section extension 56, cooperative with the overhang 53, to prevent rotary motion, as will be readily understood without iurther explanation. The bolt 55, is under the action of a compression spring 57 and the extension 56 thereof serves as an arresting stop to prevent the form 11, from rising or lifting relative to its support, as hereafter fully explained. Further, a spring influenced hard rubber butter 58, is appropriately titted to the pedestal, 50, for engagement by the rein torcement 238 on the a' vancing form carrier end to prevent elash and reduce the impact, as will be quite obvious.

liaving described the aggrouped instrumentalities embodied in this invention. and assuming that the spider 12, is intermittently rotated in a counter-cloclnvise direction, it will be readily seen, from an examination of Fig. I more particularly, that the mass of form carriers 26, are progressed through the drying corridor 10, in relatively stationary relation. This normal, or so-termed, stat-ionary position of the torm-carrie1s 26 and forms 11, does not conflict with their swiveling capacity about the bearings and is not to be construed otherwise than as featuring their tangential disposition during transit through said corridor. N ow, assuming that a form 11, has reached the position designated a, ready to emerge from the drying corridor 10, it will be readily understood that the undercut part 20 ot' the advancing upper lateral-lug 2O encounters a pin or an tit'riction roller 59, on the guide ring 535). which initiates outward swinging motion of the outrigger arm 16. This initial swing of the outrigger arm 16, projects the forwtn'd end of the lower lateral lug 19 into cooperative engagement with an upstanding antifri ction roller 60, functional to complete swinging said arm 16, and supported form 11, laterally through approximately onehundred-eighty degrees, or into the position designated Z) for stripping in the well known way while a stop 59" is effective to prevent any back-lash intermediate transfer from the pin or anti-friction roller 59 to z Lemmas a standing roller 60. Concurrent with comp etion of the lateral swing, thus imr parted to the outri ger arm 16, the form carrier 26, will ave become arrested the form 11, is held stationary and prevented from rising during the stripping operation; while the forceof the impact bee tweenthe parts 38 and 50 is counteracted by a the hardmubber cushion 58, as will be easily understood by an examination of the drawings. At the same time it is observable that, when the outrigger arm 16 occupies position ill, the lateral lug 20,has been moved into close v juxtaposition with a second roller 61,

arm steady. 0, 1 The following :1

which assists release of the latched outrigger 16, for progression with the next succeeding movementof the spider 12, to the location designated 0. During this last referred to progressive movement, it-will be apparent that the outrigger arm 16 will have swiveled from a substantially radial direction to a tangential one with the scam face 62-Fig.

V-cooperating with .a. vertical flange 63 on the guide ring :59, thereby holding said intermittent planetary movement of the spider 12, effects advancement of the outrigger arm 16 from location a to re-clothingnposition d, incident to the aforesaid cam face 62,;of the lateral lug 20, ,moving along the flange 63, and cooperationof the ca mvface 64with' an antifriction-roller 65. At the same time it is noticeable that :the outrigger arm; 16, is held relatively stationary at the position d, by: means of a spring influenced restraining device 66 The subsequent progressive movement of the spider 12, moves the toe 67 of the lateral lug 19, intocooperat'ive engagement with an antifriction roller 68, about which it rides, until the tooth -69" of the lug engages and rides around a further roller 7 0,

whereby the outrigger arm 16, is'returned into the drying corridor 10, as indicated at e. Incident to the lastdeseibed movements,

59', functionalto hold the massed form 1 carriers 26, and attached'foi'ms 11, relatively stationary during progress through the dryling corridor 10, ashereinbefore referred to.

, As-it is desirable for the iboa-rding operative when reclothingthe form 11, to be able to inspectbothsides thereof, the carrier 26 is mountedbyameans of the bolt with capacity of helico-ax'ial movement, as hereinbefore set fort-h, whereby a half-turn can b imparted under control of the cams or teeth 29, Now in order that the turned relatively positioned to impart a reverse half-turn or helico-axial movement to the form 11, thereby restoring said form to its original position, aswill be readily understood by anyone in the least conversant with the art, hence further explanation is deemed unnecessary. a I

From the foregoing description it is thought that the sequence of operations associated in the. present invention will be fully understood, while its inherent advantages are self evident. However, we desire to state that the particular embodiment described is by way of example only; hence the right is accordingly reserved to make all such reasonable changes and variations,
